Olympiaturm

This guide to the Olympiaturm in Munich starts behind an unmarked door on the observation deck, where two collectors, Herbert Hauke and Arno Frank Eser, hauled up rock memorabilia in 2004: guitars once played by Ozzy Osbourne, relics tied to Jim Morrison and Freddie Mercury, a piano signed by Elton John. It traces how a 1960s broadcast tower built to fix flickering televisions became a landmark after the 1972 Olympics, and how tight the display space stayed as the collection grew. Below you, the restaurant still turns a full circle, the way it has for decades.
